Look for Browns quarterback Brandon Weeden to be the man against Jacksonville on Sunday.

"Chances are he'll start," head coach Rob Chudzinski said in his Monday-after press conference.

Weeden replaced Jason Campbell twice during Sunday's 27-11 loss to Pittsburgh, first for one play after Campbell aggravated a rib injury, then for most of the second half after Campbell suffered a concussion.

The Browns are 1-5 in games in which Weeden has played this year, a factor — along with his poor 66.0 passer rating — in his reception among fans. He was intermittently booed Sunday.

"I understand where fans are coming from," Chudzinski said. "At the end of the day, he's a Cleveland Brown."

Campbell fell to 1-3 as the Browns' starter. He left the game after getting clocked by William Gay on a corner blitz. He had thrown for 124 yards and trailed 14-3 when he left the game for good.

He fumbled on the play, and Gay's long return set up a touchdown that made it 20-3.

Chudzinski said Campbell reported to Browns headquarters Monday morning but soon went home. He has been placed in "NFL concussion protocol."

Chudzinski did not rule him out of the Jacksonville game. If, as expected, Campbell misses the game, the Browns will need a backup quarterback, having none on the roster other than Weeden and Campbell.
